10 Claims.

My invention relates to an apparatus for and method of fumigatingrodents, chicken coops, trees, and the like.

The objects of my invention are:

First, ,to provide a simple and economical apparatus for fumigating, andone which will not readily deteriorate or get out of order;

Second, to provide a fumigating apparatus whereby the exhaust of aninternal combustion engine is utilized, and particularly where theexhaust of an automobile vehicle is utilized;

Third, to provide an apparatus of this class whereby a fumigatingsubstance is allowed to dip into a source of hot gases of combustion andthen force into the place to be fumigated, the fumigating gases beingscattered or forced into the holes or spaces desired to be fumigated byair under pressureforced at intervals into the place to be fumigated;and

Fourth, to provide a simple and novel and conomical method of fumigatingrodents, chicken coops, trees, and the like.

With these and other objects in view as will appear hereinafter, Idevised a structure having certain novel features of construction,combination and arrangement of parts and portions and a certain processof application of the elements of my apparatus, as will be hereinafterdescribed in detail and particularly set forth in the appended claims,reference being had to the ac.- companying drawing and to the charactersof reference thereon which form a part of this application, in which:

The drawing is a fragmentary diagrammatic view of an apparatus designedto perform the functions hereinbefore and hereinafter set forth.

In the drawing, 1. illustrates the internal combustion engine, and 2 theexhaust manifold thereof, while 3 illustrates the exhaust pipe connectedby the coupling 4 to the intake manifold 2, and usually connected to themufiler of the engine, (not shown). 7 V

The exhaust manifold 2 is provided with a portion 2a for receiving theexhaust gases of the last cylinder, that is, the last cylinder, beforethe gases of combustion are exhausted. Above the portion 2a is providedan enlarged portion 2b which is principally made by welding. To theenlarged portion 2b is secured a cock 5 for regulating the clipping ofthe fumigating substance into the exhaust manifold 2. To the regulatingcock 5 is secured an oil cup 6 which extends above the cock 5 and inwhich the fumigating substance is placed as will be describedhereinafter.

To the portion of the exhaust pipe 3 which is connected with themanifold 3a, is. secured, by

means of a coupling 7a, a hose section 7 which is preferably made ofgalvanized iron. The galvanized iron hose section 7 is secured by acoupling 7b to a nipple 8 which is connected bymeans of a coupling 9a toa flexible hose 9 which may be provided with a nozzle 10.

In the exhaust manifold 2 is secured a pipe 11 for feeding periodicallycharges of air under pressure to the exhaust pipe. The air underpressure is regulated by the valve 12 while the air, under pressure iscontained in a container 13 which is preferably charged with air by theinternal combustion engine 1.

The nozzle 10, which holds the hose 9, is placed in the place or holewhich is desired to be fumigated. The engine is operated and the exhaustgases together with evaporated fumigating'substance from the oil cup 6which is evaporated in the exhaust manifold 2, is directed into theplace or hole periodically, say at about two.v minutes, or so, chargesof air under pressure are directed into the space or hole to befumigated, the air directed into the intake manifold, or directed intothe hose 9 is under pressure of a few pounds, say 20 pounds. In order tofacilitate the evaporation of the fumigating substance, the oil cup 6 ispreferably placed at least abovev the portion 2a, so that all of thecylinders of the internal combustion. engine facilitate the evaporation.The connection of the air pipe 11 with the exhaust manifold 2 ispreferably an inch backwardly from the last cylinder or portion 2a.

For rodents I have found the following mixture appropriate, namely; 2parts by weight of light cylinder oil, 3 parts by weight of concentratedammonia (the last element is preferably XXX-ammonia dissolved in water).

For hog houses, chicken coops, basements, and the like, I have found thefollowing mixture appropriate: 3 parts of creoline, 3 partsofconcentrated ammonia.

-For fumigating trees, shrubs, etc., I have found the following formulaappropriate: 2 parts of light cylinder oil, 4 parts of (warm) sulphurwater.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions of my invention and certain stepsin the process of using the same, I do not wish to be limited to thisparticular construction, combination and arrangement, but desire toinclude in the scope of my invention the construction, combination andarrangement,

and the process substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In an apparatus of the class described, a source of hot gases, asource of liquid including a hydrocarbon adapted to mix With said hotgases so as to produce carbon monoxide, and flexible means for directingsaid gases and liquid vapors into the space to be fumigated.

2. In an apparatus of the class described, a source of hot gases, asource of liquid including a hydrocarbon adapted to mix with said hotgases so as to produce carbon monoxide, means for forcing air underpressure into the first source, and flexible means for directing saidgases and liquid vapors into the space to be fumigated.

3. In an apparatus of the class described, a source of hot gases, asource of fumigating liquid so arranged with the source of hot gases asto drop fuinigating liquid into the latter adjacent said source of hotgases, flexible means for directing said gases and liquid vapors intothe space to be fumigated, and means for forcing air under pressure intosaid first source.

4. In an apparatus of the class described, the combination with anautomobile, of the exhaust manifold of the engine of the automobile, asupply of fulnigating liquid connected with the manifold adjacent theconnection thereof with a cylinder of the engine whereby the liquidentering the exhaust manifold is immediately vaporized, a flexiblefumigating conductor connected with said manifold, and means for forcingthe air into said conductor.

5. In an apparatus of the class described, the combination with anautomobile propelled by an internal combustion'engine, of an exhaustmanifold connected to said engine, a flexible conductor connected tosaid manifold adapted to direct the gases issuing therefrom into thedesignated place to be fumigated, a supply of fumigating liquidconnected with this manifold opposite one of its connections with acylinder of said engine so as to be heated thereby, means forcontrolling said liquid, means for supplying said manifold withcompressed air, and means for controlling the supply of compressed airto said manifold.

6. The herein described method of preparing a fumigating substanceconsisting in producing hot gases of combustion, then mixing andvaporizing a fumigating substance with said hot gases of combustion anddirecting the gases into the place to be fumigated, and periodicallyinjecting air under pressure in said place to be fumigated.

7. The herein described method of fuinigating consisting in evaporatinga fuinigating substance in a current of burned gases of combustion, thendirecting the gases into the place to be fumigated, and periodicallyforcing air under presure into said place to be fumigated.

8. The herein described method of fumigating consisting in, vaporizing afumigating substance including a hydrocarbon in a current of hot burnedand burning gases of combustionso as to increase the carbon monoxidecontent.

9. The herein described method of fumigating consisting in, vaporizing ahydrocarbon in a current of hot burned and burning gases of combustionso as to increase the carbon monoxide content of the resulting mixture,then directing the mixture into the place to be fumigated.

10. In an apparatus of the class described, an internal combustionengine having an exhaust manifold, means for introducing a hydrocarboninto the exhaust manifold so as to contact with the hot burning andburned gases of combustion and be vaporized thereby, whereby the carbonmonoxide content is increased, and an exhaust pipe and a flexible hoseextending from said exhaust manifold.
